RATCHET MECHANISM.

SPECIFICATION forming part of Letters Patent No. 595,598, dated December 14, 1897.

Application filed March 3, 1897. Serial No. 625 ,840. (No model.)

To all whom it may concern.-

Be it known that I, ERNEST BOENING, a citizen of the United States, residing at Yonkers, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Ratchet Mechanism; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is an improved contrivance of ratchet mechanism for drills, registering mechanism,and other apparatus,whereby the ratchet-wheel is actuated both in the forward and backward movements of the operatinglever with economy of time and labor, as hereinafter described, reference being made to the accompanying drawings, in which proved ratchet mechanism contrived forworking drills and other devices. Fig 2 is a plan view of one side of the apparatus with the cover removed. Fig. 3 is a plan view of the,

other side of the apparatus. Fig. 4 is a section showing a modification of the drill mechanism. Fig. 5 is a side elevation of the apparatus applied to a hoisting-drum.

A ratchet-wheel c is mounted revolubly on a base-plate b for turning a socket, as a, for the shank of a drill, or a shaft or other means of imparting motion to anything to be intermittingly rotated, said ratchet-wheel being preferably placed with its side against that side of the base-plate, and on the opposite side of the base-plate is a reduced extension 61 of the socket through a bearing-hole in the base-plate for the socket, on which extension the operating-lever e is mounted.

The short arm of the operating-lever is coupled by a link f in a toggle-joint, with a stud g projecting through a slot h of the base-plate, which is radial to the lever-pivot, said stud adaptedto reciprocate in said slot and said joint adapted to vibrate each way across the line of movement of the stud, and on the opposite side of the base-plate the stud g is connected to the shank of a hook-pawl h, arranged in suitable relation to the ratchet wheel for actuating it when the stud is recipable form of construction in some cases. Figure l is a sectional elevation of my im- In Fig. 4 the stud d is made separately from the socket and is fixedly attached to the base-plate,so as not to revolve, and the socket has a ball-bearing a under the base-plate for reducing the friction, which may be aprefer- A locking-pawl j is attached to or form ed on the shank of pawl h, which takes effect on the ratchet-wheel when the operating-pawl h is at rest for a more positive security against wrongful movement of the ratchet-wheel without movement of the lever, especially forward, for false counting, which is a precaution that is desirable in some uses of the apparatus, as when the ratchet-wheel is utilized as part of a registering apparatus, as in my pending application, Serial No. 585,544, filed March 31, 1896, to which reference is made for a better understanding of the same.

In connection with the locking-pawlj means will be employed to lock the lever 6, so that it cannot be actuated without being unlocked-- as, for instance, a lock}; of any kind attached to the lever, so that its bolt may be shot into a socket q in the rim of the case in either position of the lever at rest.

In Fig. 5 the part ct, corresponding to the socket a of Fig. 1, is connected to a hoistingdrum for utilizing the apparatus for turning it, as for raising heavy weights by hand, and the extension-pivot m is omitted. The base-plate b is in this case secured against the lever thrusts by connection with thedrumhousing, as at t.

It will be seen that a forward-and-backward movement of the pawl 71. is effected and a forwheel by each single movement of the lever e, through the movement of pivot-joint 0, from one side to the other of the radial line in which the pawl-carrying stud 9 slides, and it will also be seen that the apparatus may be utilized for actuating various intermittinglyrotating devices, as the pointer of a register.

I claim- 1. In ratchet mechanism, the combination of a base-plate, a ratchet-wheel mounted for rotation on said base-plate for transmitting motion, a lever pivoted in the axis of said ratchet-wheel, a pawl-carrying stud reciproeating radially to the said axis, a pawl attached to said stud and adapted to actuate the ratchet-wheel, and a link coupling said pawlcarrying stud to the short arm of the lever in a toggle-joint adapted to work each wayacross the line of movement of the pawl-carrying stud substantially as described.

2. In ratchet mechanism, the combination of a base-plate, a socket or shaft pivoted on said base-plate for rotation on its axis, a ratchet-wheel attached to said socket or shaft for turning it, a lever pivoted in the axis of said socket or shaft, a pawl-carrying stud reciprocating radially to the said axis, a pawl attached to said stud and adapted to actuate the ratchet-wheel, and a link coupling said pawl-carrying stud to the short arm of the lever in a toggle-joint adapted to Work each way across the line of movement of the pawlcarrying stud substantially as described.

3. In a ratchet mechanism, the combination of a base-plate, a socket or shaft pivoted on said base plate for rotation on its axis, a ratchet-wheel attached to said socket or shaft for turning it, a lever pivoted in the axis of said socket or shaft, a pawl-carrying stud reciprocating radially to the said axis, a pawl attached to said stud and adapted to actuate the ratchet-wheel, a link coupling said pawlcarrying stud to the short arm of the lever in a toggle-joint adapted to work each way across the line of movement of the pawl-carrying stud, means to lock the lever in either of its positions at rest, and the locking-pawl for the ratchet-wheel on the ratchet-wheelactuating pawl substantially as described.

4. In a ratchet mechanism, the combination of a base-plate, a socket pivoted on said baseplate for rotation on its axis, a ratchet-wheel attached to said socket for turning it, a lever pivoted in the axis of said socket, a pawl-carrying stud reciprocating radially to the said axis, a pawl attached to said stud and adapted to actuate the ratchet-wheel, a link coupling said pawl-carrying stud to the short arm of the lever in a toggle-joint adapted to work each way across the line of movement of the pawl-carrying stud, and a feed-screw, substantially as described.

5. In a ratchet mechanism, the combination of a base-plate, a socket pivoted on said baseplate with a ball-hearing of its end against said base-plate, a ratchet-wheel attached to said socket for turning it, a lever pivoted in the axis of said socket, a pawl-carrying stud reciprocating radially to the said axis, a pawl attached to said stud and adapted to actuate the ratchet-wheel, a link coupling said pawlcarrying stud to the short arm of the lever in a toggle-joint adapted to work each way across the line of movement of the pawl-carrying stud and a feed-screw substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

ERNEST BOENING.
